摘要: A method and an apparatus for sequentially testing a series of samples in respect of the absorbency or another optical characteristic by means of a single-beam photometric system. The photometric system has a sample cell which is displaceable between a first position, in which it is in the path of light between the light source and the light-sensitive detector of the photometric system, and a second position, in which it is clear of the path of light. Immediately prior to each test a reference signal is generated with the sample cell in the second position and using the air in the path of light as a reference sample. This reference signal is stored by means of a capacitor and when the actual sample is tested with the sample cell in the first position, the stored reference signal is retrieved and compared with the signal obtained on the test. Before the testing of the series of samples is commenced the photometric system is calibrated by means of a blank sample to give equal signals for the blank sample and the air used as a reference sample.

摘要: APPARATUS FOR ANALYSIS OR OTHER TERATMENT OF A SERIES OF SAMPLES AND HAVING A CONVEYOR FOR TRANSPORTING THE SAMPLES IN SUCCESSION FROM A FIRST STATION IN WHICH REAGENTS ARE ADDED TO A SECOND STATION IN WHICH THE ANALYSIS RESULTS ARE ADDED TO A SECOND STATION IN WHICH THE ANALYSIS RESULTS ARE DETECTED. THE CONVEYOR INCLUDES A CHAIN OF RELEASABLY INTERCONNECTED LINKS WHICH SERVE TO HOLD ONE SAMPLE CONTAINER EACH. THE CHAIN IS FLEXIBLE AND RUNS BETWEEN THE STATIONS WITHOUT BEING GUIDED LATERALLY SO AS TO FOLLOW A PREDETERMINED PATH, AND THEREFORE THE LENGTH OF THE STRETCH OF THE CHAIN BETWEEN THE STATIONS AND THUS THE TIME FOR TRANSPORTING THE SAMPLES BETWEEN THE STATIONS MAY BE VARIED BY ADDING OR REMOVING LINKS. IDENTIFICATION MARKINGS ARE PORVIDED ON PREDETERMINED LINKS AND AN IDENTIFICATION SYSTEM IS PROVIDED FOR CORRELATING THE ANALYSIS RESULTS WITH THE RESPECTIVE SAMPLES.
